Title: Pressure setting mechanism
Inventor: NISHIHARA TADASHI
IPC: F15B5/00
Filed: 1978-09-28
Abstract: PURPOSE: To improve the precision of pressure setting by fixing a nozzle to a base block and thereby making a flexible connection pipe needless.  
     CONSTITUTION: A nozzle 3 is fixed to a base block 1 opposedly to a balanc beam 2. With a setting screw 5 rotated rightward, the left end of a setting spring 4 is displaced and expanded leftward, a setting input is fed to the beam 2, the gap between the nozzle 3 and the beam 2 is reduced, and the nozzle back-pressure is increased. On the other hand, a feedback spring 8 is moved rightward by the displacement of a bellows 6, to give the beam 2 a feedback force for rightward rotation about a fulcrum 21, and the beam 2 is balanced and stopped in a position where the setting input balances the feedback input. Thus, the precision of pressure setting is improved.

Inventor: MATSUSHITA SHINJI
IPC: G06T1/00
Filed: 1995-05-18
Abstract: PURPOSE: To reduce the influence of image noise and to stably and accurately detect an edge by determining a retrieval range by using a second-order differential coefficient and a specific threshold value, detecting the coordinates of the largest value of the absolute value of the second-order differential coefficient and regarding it as the coordinates of the edge. CONSTITUTION: In an image memory 28, the digital signal of line image data consisting of a displacement signal of one scan by a probe 18 is stored, and the line image data are inputted to a CPU30 from the image memory 28. The CPU30 performs a smoothing filter process to remove noise from the line image data. Then, second-order differential coefficient is calculated from the line image data. Calculation noise is removed from this secondary second-order differential coefficient by performing the smoothing filter calculation again.  Then, the secondary second-order differential coefficient is compared with a specific threshold value and the X coordinate where the curve representing the secondary second-order differential coefficient crosses the threshold value is detected to determine the retrieval range, and the maximum value when the coefficient is plus or the smallest value when negative is detected and the edge detection is performed by regarding the X coordinate as the edge.

Title: Segment seal
Inventor: WASHIDA AKIRA
IPC: F16J15/24
Filed: 1978-09-27
Abstract: PURPOSE: To provide a segment seal, in which a push ring having packing fitted around its outer circumference for damping and sealing purposes is held in forced contact with the side face of an annular member by means of a resilient member, whereby it is enabled to improve sealing performance, heat resistnace, low temperature resistance ans productivity.  
     CONSTITUTION: Fluid X is not permitted to pass through the outer circumference of push ring 15 and also not permitted to pass through contact surfaces C1, C2, C3 and C4. Further, contact surface 24 between the inner circumferential surface of segmental plates 13 and the outer circumferential surface of annular member 9 does not permit passaing of fluid X, and by combining segmental members 10 in suitable manner, their contact surface 25 also does not permit passing of fluid X. Therefore fluid X is obliged to pass through selaing surface S. However, since arrangement is such that contact pressure at the sealing surface S is high, leakage of fluid X through the surface S can be minimized and thus sealing performance of the segment seal can be improved as a whole. Further, because of the arrangement that clearance can be adjusted by spring 23, heat resistance and low temperature resistance of the seal can be also improved.

Filed: 1987-05-18
Abstract: PURPOSE:To easily prepare cleaning and soaking liquid which is safe even when water from water supply etc., is used by processing the water by adding ion exchanger particulates and a sequestering agent, and filtering the processes water. CONSTITUTION:The ion exchanger particulates and sequestering agent are added to the water for the processing. Then the side part of a container main body 10 is clamped and then the liquid contained in the main body 10 is filtered by a porous hollow year membrane 28 which has a fine hole diameter for stopping particles of at least >=1mum constituting a hollow yarn module 26 to obtain the soaking liquid. This soaking liquid reaches an outflow port 22 through a communication space 32 provided in a cap 18 and is discharged therefrom. When the main body 10 is released from being clamped after the filtering operation, the pressure in the main body 10 is reduced by means of the elastic restoration of the main body 10, so external air is guided to the membrane 28 of the module 26 from the outflow port 22 through the space 32 to flow in the main body 10 through its hydrophobic part and the pressure in the main body 10 returns to normal pressures and the main body 10 restores itself to its original shape. Thus, the soaking liquid is easily prepared with water from water supply, etc.
